Multi-antenna systems provide advantages in terms of link quality and multiuser access capabilities, which can be achieved by using schemes as multibeam opportunistic beamforming. This scheme only requires partial channel ...

In the last decade, the Wireless Local Area Network (WLAN) market has been experiencing
an impressive growth that began with the broad acceptance of the IEEE 802.11 standard [1].
Given the widespread deployment of WLANs ...

A cross-layer based dynamically tuned queue length
scheduler is presented in this paper, for the Downlink of multiuser
and multiantenna WLAN systems with heterogeneous traffic
requirements. An opportunistic scheduling ...

Scheduling in a Downlink channel based on partial Channel State Information at the Transmitter (CSIT) is carried out through an opportunistic technique. Within a more practical perspective, this paper first presents a ...
